To all `whom it may concern: 1

l `Beit known that I, HENRY HAAK, a citizen of the -United States,residing at Myerstown, `in the county of Lebanon and State of yPennsyl-Vania, have-invented certain new and useful Improvements inMillQStrainers, of which the following is aspeciication, reference beinghad therein to the accompanying drawings, in whicha Figure 1 is a sideelevation, partly insection, of a milk-strainer constructed in accordance with my'invention. Fig. 2 is a vertical section of the same, andFig. 3 a modification hereinafter described.

Like letters refer to like parts in all the iigures. Y

The object of this invention is `to provide means for the cooling anddeodorization of milk during the operation of straining the same, as itusually occurs-that is, when the milk is fresh and contains animal heatand odor. Heretofore milk has been strained as rapidly as possible into.cans for shipping to creameries, cheese-factories, and more distantdestinations, and therefore contains odorrand animal heat, which renderthe milk more liable to rapid deterioration and premature sour- Theprinciple of operation upon which my invention is based is `that of nelysubdividing o r sheet, and of exposing one side thereof to the air toextract any odor in the milk` and to expose the opposite side thereof tothe action or influence of any suitable reirigerative subtance, and tocontinue this principle of operation during the filling of the cans fortransportation.

To adapt my invention to practical use, I employ an inverted cone, A,the apex of which is of a size whichcan be loosely inserted into anyordinary `shippingcan (as E) or other desired vessel, and the base ofwhich is pro.d vided with a series of supporting-rods, arms, orbrackets, a, whereby the cone may be supported above the can or vesselupon a framef anopening, b, for the reception of the cone. The apex ofthe cone being closed, it forms a chamber for the reception and theretention low.

means. The walls or body of the cone may 4be either plain or corrugatedto increase its flange, c, which embraces or is embraced by a similarflange, a, formed on the cone.` In the former instance anoutwardly-projecting shoulder, a2, is formed .on the cone, and in thelatter instance an inwardly-projecting shoulder, c2, isformed on theflange c of the cover or strainer 5 or it may be formed in the body ofthe strainer, the object of projecting` the shoulders being to preventthe passage of milk from the strainer into the cone. The bottom c1 ofthe strainer is upwardly curved or conveX to facilitate the drainage ofmilk therefrom. The cylindrical body of the strainer may be tapering orstraight, and is provided near `the bottom and extending nearly aboutthe same with reticulated openings ct. About the body of thestrainer isa sleeve or hoop, D, the lower edge of which, atleast, is adapted to4snugly fit the body at the reticulated open- `whereby the -cooling andstraining may be in terrupted at will, this being a secondary functionof the sleeve and collar, the primary function of the same being that ofa gage and deiiector, respectively, for as .the sleeve is more or lessdepressed over the openings c4 more or less milk is prevented .frompassing therethrough, and that which does pass therethrough strikesagainst the inner surface of 9o the collar, and is directed inwardlyupon the cone and forms thereon an enveloping sheet `or stream `of milk,which adheres to and trickles or flows slowly down the outer surfaceofthe same andinto the can or vessel be- A refrigerative substance beingwithin the cone cools the body thereof and absorbs animal heat from themilk while it is in contact with the outer surface thereof, and by thefinely-divided condition of the milk and its simultaneous completeunobstructed exposure to the atmosphere deleterious odors are eliminatedand evaporated.

In Fig. 3 I illustrate an induction-pipe, A',

IOO

and an eduction-pipe, vA, Wherebya continuous stream of Water may beemployed as' the refrigerative substance.

It is apparent that the sleeve D alone Will in a measure prevent milkfrom passing out- Wardly beyond the cone.' Therefore I do not restrictmyself to the partial necessity of employing the collar d.

The springs ci are used in connection with a flaring strainer to holdthe sleeve D in desired positionsby friction.

Having described my 'invention and its operation, what I claim is l. Thecombination of an inverted coneshaped refrigerating chamber and a`milkstrainer constructed as a cover to the same, and located andarranged to deliver milk therefrom against a flange and onto the outersurface of said chamber, substantially as and for the purpose set forth.

2. The combination of an inverted coolingcone,- a strainer surmountingthe saine, and a sliding gage or sleeve, substantially as specined.

3. The combination of a shipping-can, an

inverted co olingcone, and a strainer surm ounting the cone, andconstructed 'as acover to the same, and arranged and located to delivermilk in a thin sheet, stream, or spray upon the outer surface of thecone, and means for regulating the flow of the milk, substantially asspecified.

4. The combination of the cone A, provided with the arms a, the frame B,and the strainer Y- .o HENRY l-IAAK. Vitnesses:
